The present invention relates to a method for securing qualitative and quantitative information of a high molecular weight additive in a polymer resin by using consecutively connected size-exclusion chromatography (SEC)-pyrolysis-gas chromatography/mass spectrometry(Py-GC/MS), and an analysis system used therefor. By analyzing a high molecular weight additive having a specific residue by pyrolyzing the high molecular weight additive into a low molecular weight compound, the present invention can secure the structure and content analysis information of the high molecular weight additive, which were difficult to secure by means of conventional analysis methods. La présente invention concerne un procédé permettant de sécuriser des informations qualitatives et quantitatives d'un additif de poids moléculaire élevé dans une résine polymère à l'aide d'une chromatographie d'exclusion de taille (SEC) connectée consécutivement-pyrolyse-chromatographie en phase gazeuse/spectrométrie de masse (Py-GC/MS), ainsi qu'un système d'analyse utilisé à cet effet. Par l'analyse d'un additif de poids moléculaire élevé présentant un résidu spécifique par pyrolyse de l'additif de poids moléculaire élevé en un composé de faible poids moléculaire, la présente invention peut sécuriser la structure et les informations d'analyse de contenu de l'additif de poids moléculaire élevé, difficiles à sécuriser au moyen de procédés d'analyse classiques. 본 발명은 연속적으로 연결된 크기 배제 크로마토그래피(SEC)-열분해-가스 크로마토그래피/질량분석기(Py-GC/MS)를 이용해 고분자 수지 중 고분자량 첨가제의 정성적 및 정량적 정보를 확보하는 방법 및 이에 사용되는 분석 시스템에 관한 것으로, 특정 잔기를 갖는 고분자량 첨가제를 낮은 분자량의 화합물로 열분해시켜 분석함으로써 종래 통상 사용되었던 분석방법으로 확보하기 어려웠던 고분자량 첨가제의 구조 및 함량 분석 정보를 확보할 수 있다.
